If you use the inner chainring you will not need to redish at all, you could even use your outer with little problem. I'd be very surprised if you're strong enough to need the outer ring. The spacing on your 5cog/10 spd bike is 120 mm., which, if memory serves is the same as purpose built track wheels. I turned an old Bianchi w/126 mm spacing into a "fixie" and stuck the "road spaced cogs" on a seven spd hub and used the same chain no problem, all I had to buy were the cogs with "road [thickness]teeth) 16,17,18,19 and 20 tooth used with a 39 tooth innner ring. ( I already had a BB lock ring I used as the hub/cog lockring. I saved the extra chain derailleurs etc. I could change it back to multi-speed in less than an hour.
